The perimeter of any shape is the length of all the sides added up:
1. For the rectangle
[tex]6 + (3x - 1) + (3x - 1) + 6 = 6x - 2 + 12 =6x + 10[/tex]
2. For hexagon
[tex]10.2 + (x+4)+(x+4)+10.2+(x+4)+(x+4)=4x + 16 + 20.4=4x + 36.4[/tex]

Answer:
Step-by-step explanation:
ax² + bx + c = 0
[tex]x_{1}[/tex] = [tex]\frac{-b - \sqrt{b^2 -4ac} }{2a}[/tex]
[tex]x_{2}[/tex] = [tex]\frac{-b+\sqrt{b^2 -4ac} }{2a}[/tex]
~~~~~~~~~~~~~~~~~~~
x² + 4x - 16 = 0
a = 1 , b = 4 , c = - 16
[tex]x_{1}[/tex] = ( - 4 - [tex]\sqrt{16+64}[/tex] ) ÷ 2 = - 2 - 4√5
[tex]x_{2}[/tex] = - 2 + 4√5

What is 34107.12 to the nearest half centimeters? 
Answer:
34107cm
Step-by-step explanation:
f(x) = 1.1–4x when x = – √2
Answer:
f(x)=2x^2+4x+6
f(x)=2(x^2+2x)+6
f(x)+?=2(x^2+2x+?)+6
f(x)+?=2(x^2+2x+1)+6
f(x)+2x1=2(x^2+2x+?)+6
f(x)+2=2(x^2+2x+1)+6
f(x)=2(x+1)^2+6-2
f(x)=2(x+1)^2+4
Answer:
f(x)=2(x+1)^2+4

Carly needs $149 to buy a skateboard. She already has $52. She earns money washing cars for $20 a car.
Carly says that if she washes 5 cars she will have enough money to buy the skateboard.
Use the drop-down menus to explain how to solve this problem.
First, multiply
Choose...
× $20 to find how much money Carly will earn washing cars. Then add this amount to
Choose...
to find how much money Carly has in all. Finally,

the total to the cost of the skateboard.
Answer:
Answer:
$149 - skateboard price
$52 - carly's money
$20 × 5 cars = $100
$100 + $52 = $152
$152 - $149 = $3 left

Estimate the values for the two
missing quantities. Enter your
estimates into the blank boxes in
the table.
The first missing quantity is force due to gravity, and it is 215.1 N.
The second missing quantity is distance between the statellite and the Earth, determined as 6,000 km.
Force between two massesThe force between two masses is determined by applying Newton's law of universal gravitation as shown below;
[tex]F = \frac{GMm}{R^2}[/tex]
where;
M is mass of Earth = 5.97 x 10²⁴ kgm is mass of the satelliteR is the distance between the satellite and the EarthG is universal gravitation constantFirst missing quantityThe first missing quantity is force due to gravity, and it is calculated as follows;
[tex]F = \frac{(6.67 \times 10^{-11} ) \times (5.97 \times 10^{24}) \times (700)}{(36,000 \times 10^3)^2} \\\\F = 215.1 \ N[/tex]
Second missing quantityThe second missing quantity is distance between the statellite and the Earth,
[tex]R^2 = \frac{GMm}{F} \\\\R^2 = \frac{(6.67 \times 10^{-11})(5.97 \times 10^{24})(1000)}{11,000} \\\\R^2 = 3.62 \times 10^{13}\\\\R = 6,000 \ km[/tex]

Which graph represents the parametric equations x(t) = t – 4 and y(t) = t2 + 5 for –1 ≤ t ≤ 2?
Which graph indeed?
Eliminate the parameter:
x = t - 4 ⇒ t = x + 4
⇒ y = t² + 5 = (x + 4)² + 5
which is the equation of a parabola with vertex at (-4, 5) and opening upwards, plotted with domain
-1 ≤ t ≤ 2 ⇒ -1 ≤ x + 4 ≤ 2 ⇒ -5 ≤ x ≤ -2

multiply both sides by 2
5x = 20
divide both sides by 5
x=4
Answer:
x=4
Step-by-step explanation:
5x-2=18 (multiply 9 with 2=18)
5x=18+2 (move 2 to the other side)
5x=20 (add 18 and 2=20)
X=4 (divide 20 and 5 =4)

Answer:
Step-by-step explanation:
for number 8 we have to use the equation πr^2, so plugging 9 into the equation would give us π(9^2). squaring the 9 gives us 81, and 81 times π equals ~25.
for number 9 we need to use the same equation, πr^2 to find the area, but since we are given the diameter we do not need to use r^2. Instead, we can use π(106) which gives us 333.
